Application of cave-scale rock degradation models in the imaging of the seismogenic zone
journal contribution
posted on 2016-04-08, 00:00 authored by J M Reyes-Montes, Bre-Anne SainsburyBre-Anne Sainsbury, J R Andrews, R P YoungMicroseismic monitoring provides insight into the location and extent of rock-mass fracturing induced by cave mining, enabling interpretation of the cave profile and validation of predictive numerical models. Source location uncertainties can lead to misinterpretation of the inferred characteristics of the fracture network. One principal source of uncertainty is the velocity model used to invert the location algorithm. Large-scale 3D numerical models of modulus changes across a caved mass can represent such complexities in the location algorithms, allowing more accurate interpretation of the microseismic activity. A Northparkes mine case study applies this advanced approach to microseismic data interpretation.
